The MacroFactor Equation
- The initial expenditure calculation now uses the MacroFactor Equation to determine the user’s basal metabolic rate (BMR). This new equation improves upon the strong foundation of existing BMR science by accounting for metabolic adaptation during weight loss, non-linear decrease in metabolic rate due to aging, and other factors. Shout out to Greg Nuckols for developing the MacroFactor equation and doing a thorough review of the literature on the latest BMR science.
- You can switch to using the MacroFactor Equation for your initial expenditure estimate by going to More > Expenditure > BMR . As a note, if it has been more than 30 days since you started using the app, the impact of the initial expenditure is likely to be minimal, as the app is using your nutrition and weight data to determine your current expenditure.
- The onboarding has been revamped to use the MacroFactor equation and align the experience with our new design system.
Community Note: The release will gradually roll out to Android and iOS devices. It will take 1-7 days for the update to make it to everyone. After 1 day, any iOS user should be able to manually initiate the update from the App Store.
